To have someone declared a vexatious litigant, you file a motion in the court where your current case is pending, attach certified records proving a pattern of abusive filings, serve the opposing party, and persuade a judge at a hearing that restrictions on that person’s court access are warranted. The process is deliberately demanding because it limits a fundamental right, but when the evidence is strong it produces one of the most effective orders available against litigation harassment: a pre-filing injunction that blocks the person from suing again without judicial permission.
The Pattern You Have to Prove
A vexatious litigant designation isn’t about losing lawsuits. It targets people who use the court system as a weapon, and judges evaluate the overall pattern rather than any single filing. The criteria vary by jurisdiction, but the same indicators show up across them.
- Volume of failed self-represented cases. Some states set specific thresholds, such as five or more losing pro se cases within a defined lookback period, or cases left dormant for years without going to trial.
- Relitigation of decided issues. Repeated attempts to reopen or challenge cases already resolved against the person, often against the same defendants and over the same facts.
- Frivolous filings within a single case. Flooding one lawsuit with meritless motions, unnecessary discovery, or procedural maneuvers meant to exhaust the other side rather than move any real claim forward.
- A prior vexatious litigant finding in another court, state or federal.
Intent runs through all of it. Courts separate people who file bad lawsuits because they don’t understand the law from people who file them to harass. Threatening messages, a history of targeting the same person, and filings timed to unrelated disputes all push the analysis toward harassment.
Which Legal Standard Applies
There is no single federal vexatious litigant statute. Federal courts draw on two sources of authority: Federal Rule of Civil Procedure 11 for sanctions on frivolous filings, and the All Writs Act, which gives federal courts broad power to issue orders necessary to protect their jurisdiction.1Office of the Law Revision Counsel. 28 USC 1651 – Writs
Under the All Writs Act, federal courts can issue pre-filing injunctions against vexatious litigants, but they must first formally declare the person vexatious. Most circuits apply a multi-factor test. The exact factors differ, but courts typically weigh the litigant’s history of harassing or duplicative lawsuits, whether there was any good-faith basis for pursuing them, the burden on the courts and opposing parties, and whether less drastic sanctions would work. Some circuits also consider whether the litigant was represented by counsel and whether they got notice and a chance to respond before the restriction was imposed.
On the state side, roughly a dozen states have enacted specific vexatious litigant statutes that spell out criteria, filing procedures, and available remedies. The rest handle abusive litigants through their courts’ inherent authority or general rules against frivolous filings. Check whether your state has a dedicated statute; if it does, the statute controls the criteria and process. If it doesn’t, you’ll be asking the court to use its inherent powers, which requires the same kind of strong factual showing.
Building the Evidence File
The burden is on you to prove the pattern. Judges won’t investigate the person’s litigation history on their own, and motions fail most often when they rely on narrative descriptions instead of documentation.
Start by pulling certified copies of every lawsuit, motion, and pleading the person has filed against you or others you know about. The clerks of the courts where those cases were filed can provide them. These records form the factual backbone of the motion by showing volume, timing, and subject matter.
Get certified copies of the court orders from those prior cases too, especially judgments, dismissals, and any rulings where a judge explicitly found a filing frivolous or meritless. An order that says “dismissed as frivolous” carries far more weight than your own characterization.
Preserve direct communications from the litigant as well. Emails, letters, voicemails, and text messages can reveal a motive to harass rather than resolve any real dispute. A message saying the person plans to keep suing until you go bankrupt tells a judge something a stack of dockets cannot. Organize everything chronologically so the pattern is immediately visible.
Filing and Serving the Motion
The motion is filed in the court where your current case is pending. It’s typically captioned as a motion to declare the opposing party a vexatious litigant, though the exact name varies. The body of the motion lays out the legal standard that applies in your jurisdiction and then walks the judge through the evidence, explaining how each exhibit shows the pattern.
Attach the supporting documents as numbered exhibits with clear labels, such as “Exhibit 1: Complaint in Smith v. Jones, Case No. 2023-CV-1234, filed January 5, 2023.” File the motion and exhibits with the clerk.
After filing, serve the opposing party with a complete copy of the motion and every exhibit. Someone facing restrictions on their court access has a constitutional right to know about the motion and respond, so follow your jurisdiction’s rules for service of process carefully. The court will then set a hearing.
What Happens at the Hearing
Both sides present arguments. You walk the judge through the evidence of abusive filings, and the opposing party gets a chance to explain why the filings were legitimate, why the pattern isn’t what it looks like, or why restrictions would be inappropriate. Courts can consider written submissions, oral argument, witness testimony, and sworn statements.
Expect the opposing party to argue that the motion violates their right to access the courts. Judges take that argument seriously, because the right to petition the government through the courts is rooted in the First Amendment and the Due Process Clause. That’s why the evidentiary bar is high. Your task at the hearing is to show that the person’s conduct has crossed from exercising a constitutional right into abusing it.
In jurisdictions that require a finding tied to the current case, the judge may also assess whether the litigant has a reasonable probability of winning the pending lawsuit. A “no” on that question strengthens the case for restrictions.
What the Court Can Order
The most common remedy is a pre-filing order. It bars the person from filing any new lawsuits or motions without first getting permission from a designated judge, who screens proposed filings before they can proceed. The clerk is instructed to reject filings from the individual unless they carry judicial authorization. Filing in violation of a pre-filing order can result in contempt of court.
Courts can also require the vexatious litigant to post a security bond to cover the defendant’s anticipated legal costs in the pending case. The judge sets the amount case by case. If the litigant fails to post it, the court can dismiss the pending case.
Some states maintain public registries of people subject to pre-filing orders, and those lists are shared with court clerks statewide. Where these registries exist, they prevent a designated person from simply walking into another courthouse and starting over. Not every state keeps one.
Lesser Sanctions Worth Considering
A full vexatious litigant motion isn’t always the right first move. Federal Rule 11 provides a more targeted remedy for individual frivolous filings. Every attorney or self-represented party who signs a court filing certifies that it isn’t being submitted to harass, cause delay, or run up costs, and that the legal contentions are warranted by existing law.2Legal Information Institute.

When someone violates that certification, you can file a separate motion for sanctions. Rule 11 has a built-in safe harbor: you serve the sanctions motion on the opposing party, and if they withdraw the offending filing within 21 days, you can’t bring the motion before the judge. If they don’t withdraw it, the court can impose monetary penalties and order payment of your reasonable attorney’s fees.2Legal Information Institute.

In federal court, 28 U.S.C. § 1927 adds another fee-shifting tool. A court can require any attorney or admitted party who unreasonably and vexatiously multiplies the proceedings to personally pay the excess costs and attorney’s fees caused by their conduct.3Office of the Law Revision Counsel. 28 USC 1927 – Counsel’s Liability for Excessive Costs
Sanctions orders under Rule 11 or § 1927 often become stepping stones. A record of prior sanctions strengthens a later vexatious litigant motion by showing that lesser remedies didn’t stop the behavior, which is one of the factors federal courts explicitly consider.
How Long the Designation Lasts
A vexatious litigant designation generally doesn’t expire on its own. Pre-filing orders stay in effect indefinitely unless a court vacates them. The person subject to the order can petition the issuing court to lift it, but they typically need to show a material change in circumstances, not just the passage of time.
Some jurisdictions limit how often the designated person can ask for removal. If the court denies a request to vacate the pre-filing order, the litigant may be barred from filing another removal request for 12 months, which keeps the removal process from becoming another vehicle for abusive filings.
If the person landed on a statewide registry, removal from the list requires the original court to issue an order vacating the pre-filing order. The registry administrator won’t remove a name based on time alone.
Practical Considerations
Hiring an attorney is worth serious thought even if you’ve been handling the underlying case yourself. These motions involve compiling records from multiple courts, meeting jurisdiction-specific procedural requirements, and arguing constitutional questions. An attorney who has brought them before knows what your court expects and which evidence carries the most weight.
Filing fees for the motion are usually modest, comparable to any other civil motion. The real cost is the time it takes to gather certified copies from potentially several courthouses. Start that early; records requests from other courts can take weeks.
Keep expectations realistic. Courts are reluctant to restrict anyone’s access to the judicial system, and they should be. A motion built on two or three lost lawsuits and some angry emails probably won’t succeed. The motions that win are the ones where the judge looks at the evidence and sees someone who has been systematically weaponizing the legal system, filing case after case with no legitimate purpose. If that’s what you’re facing, the law gives you a real remedy.
